| 摘 要： | 为改善方形薄壁钢管混凝土矩柱的力学性能。本文提出了设置纵向劲肋的截面形式,进行了3种截面形式共有9个短柱试件的轴压试验。通过对各种截面形式短柱的试验现象、荷载-位移曲线及极限承载力等的研究,证明纵向加劲肋可有效提高薄壁钢管混凝土短柱的静力性能。

| Abstract: | In order to improve mechanical behavior for the stub-column of concrete-filled square thin-walled steel tubes(CFTST),new section types with longitudinal ribs have been proposed.The 9 specimens with 3sections are tested under axial load.The test phenomena,the ultimate capactity and the load-deformation curves are studied.The results indicate that the longitudinal ribs can remarkably improve the static behavior of CFTST. |
